We have presented you the sequence in which constructors and destructors get called in single and multiple inheritance.
*Constructor and destructor in single inheritance:
->Base class constructors are called first and the derived class constructors are called next in single inheritance.
-> Destructor is called in reverse sequence of constructor invocation i.e. The destructor of the derived class is called first and the destructor of the base is called next.
*Constructor and destructor in multiple inheritance:
-> Constructors from all base class are invoked first and the derived class constructor is called.
Order of constructor invocation depends on the order of how the base is inherited.
*Constructor and destructor in single inheritance:
->Base class constructors are called first and the derived class constructors are called next in single inheritance.
-> Destructor is called in reverse sequence of constructor invocation i.e. The destructor of the derived class is called first and the destructor of the base is called next.
*Constructor and destructor in multiple inheritance:
-> Constructors from all base class are invoked first and the derived class constructor is called.
Order of constructor invocation depends on the order of how the base is inherited.
-> However, the destructor of derived class is called first and then destructor of the base class
